What is the purpose of using an insulated tool?

Using an insulated tool primarily serves the critical purpose of reducing the risk of accidental electrical shock. When working with or near live electrical components, having tools that are insulated ensures that the user is protected from electrical currents that could cause serious injury or even be fatal. The insulation acts as a barrier, preventing the flow of electricity through the tool to the user, thereby enhancing safety in a potentially hazardous environment.

While tools with enhanced grip or those designed to prolong lifespan can improve usability or durability, these features do not provide the specific protection against electrical hazards that insulation does. Similarly, aesthetic considerations do not play a role in the functionality or safety of a tool in electrical work. Hence, the use of insulated tools is fundamentally focused on safeguarding the user from electric shock.
